Important material properties can be explained at the level of quantum physics - for example, whether a material conducts electricity or not. Analysing such quantum states has now revealed that there ...

Certain energy ... conductors and insulators than previously thought." More information: Juraj Krsnik et al, Local correlations necessitate waterfalls as a connection between quasiparticle band ...

Noble gases such as helium and neon are poor conductors of electricity, so we call them electrical insulators ... valence band (that is, the energy embodied in the highest-energy electron that ...

Topological insulators (TIs) are among the hottest topics in condensed matter physics today. They’re a bit strange: their surfaces conduct electricity, yet their interiors do not, instead acting as ...

Topological insulators (TIs ... turning their focus to the material's band structure. Quantum mechanics tells us that the electron energy levels in an isolated atom are quantized—that is ...

Through materials science, we can tailor existing substances or engineer completely novel materials to generate new and ...

At most speeds, an electron must be in either the higher or lower energy band. However, an electron can have ... revealing more complexity between electrical conductors and insulators than previously ...

Abstract: This study focuses on abnormal breakdown issues observed during the practical operation of D-mode GaN-based metal insulator semiconductor high electron mobility transistor ... a discrepancy ...

With very high frequency magnetic fields (such as those from X-rays), because of the exceptionally high rate at which the forces alternate, the wave generated can cause energy to be ... (which could ...
